Production Processes Of Power Cable
To ensure superior quality, JOCA operates fully digitalized and automated production lines for power cables. Specifically, this comprehensive workflow covers conductor stranding, insulation extrusion, metallic screening, and final sheathing. Moreover, intelligent systems actively monitor each stage to ensure stable performance and consistent product quality. In addition, the factory utilizes advanced testing facilities, such as partial discharge testing, tensile testing, and spark testing. Consequently, these rigorous measures guarantee that every delivered cable strictly meets international standards.
Packing For Shipment
To meet various transportation needs, there are many methods of packaging that can be used.
Have more questions?
Q: What is the primary application for these cables?
A: These are the backbone of Low Voltage distribution networks (0.6/1kV). They are specifically designed for municipal power supply, subscriber networks, and power stations where you need a robust underground cable that also offers interference shielding.
Q: What makes the "CW" (Corrugated Concentric) conductor special?
A: This is the key feature. Unlike standard straight copper wires, the “CW” conductor is applied in a wave (Ceander) pattern. This allows installers to spread the outer wires apart to access the inner cores without cutting the neutral/earth conductor. It makes creating branch connections (T-joints) much faster and safer, especially for house service connections.
Q: Where can I install them?
A: They are versatile. You can bury them directly underground, lay them in concrete cable ducts, submerge them in water, or run them indoors. The PVC sheath is built to handle open-air environments as well, provided it’s not subjected to constant mechanical impact.
Q: Does it act as a protective screen?
A: Yes. The concentric copper layer acts as a combined PE or PEN conductor. Additionally, because it surrounds the phase conductors, it provides an effective earthed screen against accidental contact. If a digger hits the cable, it hits the earth screen first, tripping the protection instantly.
Q: How does it compare to standard NYY cables?
A: It offers higher safety and functionality. While NYY is just insulated power, this cable (likely NYCWY) adds that concentric conductor layer. This provides better mechanical protection and necessary shielding for control impulses or data if run nearby.
Q: What is the reliability advantage for jointing?
A: As mentioned, the ability to make joints without cutting the conductor is a game-changer for grid reliability. Every time you cut a neutral to make a joint, you introduce a potential failure point. The CW design eliminates that risk, ensuring the neutral path remains solid and continuous.
Q: What are the voltage and standard ratings?
A: These are rated for 0.6/1 kV and manufactured in strict accordance with DIN VDE 0276-603 and IEC 60502-1.
Q: How do I get a quote or technical datasheet?
A: Send us your project requirements directly. We need to know the cross-section (e.g., 4×150/70), drum length, and whether you need the Ceander (CW) or standard concentric design. Our engineering team will return a spec sheet and offer within 24 hours.
